Stainless Steel 904L Flanges are premium-grade components widely used in corrosive environments where both strength and durability are crucial. At Adinox Overseas, we specialize in manufacturing and exporting Stainless Steel 904L Flanges that conform to the highest global standards. These flanges are produced using superior quality raw materials and cutting-edge technology to ensure long-lasting performance in aggressive chemical environments, including sulfuric acid, phosphoric acid, and other harsh oxidizing agents. SS 904L is an austenitic, non-stabilized grade with low carbon content, offering exceptional corrosion resistance, especially in chloride-rich conditions.
Our SS 904L Flanges meet the specifications of ASTM B649 and carry the UNS number N08904, ensuring compliance with international benchmarks. They are widely recognized for their toughness, weldability, and resistance to stress corrosion cracking and pitting. These flanges are widely used in industries like chemical processing, marine applications, power generation, pulp & paper, oil & gas, and heat exchangers. Whether it’s a coastal refinery or an acid treatment plant, Stainless Steel 904L Flanges provide excellent reliability and performance under extreme temperature and pressure conditions.
